is warm, but its rate of collapse is nowhere near Jupiter’s, and the
warmth is not even close to enough for supporting life on Titan any
more. It is possible that Titan’s people have migrated in to Saturn’s
clouds, and are living in anti-mass supported cities in those clouds -
that is up to the play-group/GM to decide. It would be extremely hard to
detect them if you were not looking specifically for them, and
virtually impossible to escape Saturn’s gravity well if you went in to
Titan is an iceball, about the size of
Luna and the Galilean moons of Jupiter. There is no life on the surface -
everything is frozen. The atmosphere would still be breathable. The old
Titan cities are way down under the ice, some of them smeared by
glaciers, and some crushed by the weight of the ice above them.
possibility exists that there may be a Titan city down under the ice,
protected by a shell and warmed by geothermal heat produced by tidal
forces. If so, the Titans living inside may be degenerate and devolved.
According to the Galileani, who knew them when their culture was fading,
the Titans were evolved from a kind of land octopus.
The Neptune System
is cold, with no residual warmth at all left from gravitational
collapse. Heat differentials do not pump energy through the atmosphere.
Compared to stormy Jupiter and Saturn, Neptune is placid.
was once habitable, like Titan, but the time it was habitable is so
long in the past that only the Titans may have met them, and they did
not tell the Galileani about them. Titan’s cities are crushed and
smeared under mountains of ice, and there is no possibility anything
still exists of that culture.
